I am doing a reno job in a mobile home and one issue is that the toilet flush is quite slow. I had to remove some on the flooring around the toilet and saw that the drain from the toilet to the stack and beyond is actually on an up hill grade.I can't move it much and the best I can do is to get it roughly level. Would this help or might there be another issue? Do all toilets flush with the same or similar velosity? Best guess and/or suggestions are welcome.

Having it flat is better than opposite assuming it isn't going up and down and up and down further on down the line, but there are no guarantees on a flat drain line. :wink:

It would be worth your while to correct the grade issue. 1/4" per foot inside the building.

It had the correct pitch when originally installed. First thing I would do is find out why it is reversed pitched. The solution might become obvious then

Agreed, this was my first thought. The sections that are inside the construction or inside the frame should have the proper pitch - if not, why not? Is the trailer itself level? Are you sure it's not the toilet - dump a bucket of water in it and see how it drains.

I've worked on several mobile homes (maintained them as rental units). Plumbing is usually pretty reliable if the trailer is level and well connected to the sewer connection. With one notable exception for those with front kitchens - the line from the sink has a long run with minimal drop - and gets clogged with grease over the years.
